Are you on 37s??? If so are you rubbing, how much are you rubbing and where? What suspension setup are you running? (Im interested in the RPG adjustable collars) Did you put a larger block in the rear or go to deaver leafs...or something else Im unaware of? Are you running 37x13.50s or 37x12.50s? Pros and cons with your decision is appreciated as well! Thanks in advance!
